FEED-WATER H EATER.

SPECIFICATION forming part. of Letters PatentNo. 330,612, dated November 17, 1885.

Application filed May 29, 1885.

T0 aZZ whom, it may concern:

Be it known thatwe, JOHN O BRIEN and SAM- UEL J. WEAVER, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in FeedWVater Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a side elevation of my improved heater. Fig. 2 is a vertical longitudinal section of the heater, taken on line 2 2, Fig. 3; and Fig.3 is a vertical transverse section taken on line 3 3, Fig. 2.

My invention relates to an improved apparatus for heating feedwater for steam-boilers, &c.; and my invention consists in features of novelty hereinafter fully described,and pointed out in the claims.

Referring to the drawings, A represents a horizontal receiver, provided at each end with a steamchamber, B, formed by outer heads, 0, and inner heads, D, the inner heads being connected by tubes I, through which steam passes from one chamber to the -other,as shown by the featherless arrow, Fig. 2, the exhauststeam from the engine entering .one of the chambers through a pipe, J, and escapes from the other through a pipe, L. The heads Care removable, being connected to the receiver by bolts M, so that they can be taken off to per mit access to the interior of the receiver,when desired, for repairs, &c.

N represents the cold-watersupply pipe, provided with a valve, 0, and which preferably extends down a distance into the receiver, as shown. The water discharged therefrom is thus carried a distance below the top of the receiver, and by the force with which it is dis valve, T. As the water passes from the re- Serial No. 167,070. (No model.)

cated beneath and parallel with the receiver, the upper part of said mud-drum being cut away throughout its whole length, and the bottom part of said receiver being correspondingly cut away,so as to form direct communication between them. By this means the muddrum is made to constitute the bottom of the receiver, the two being united by angle-irons X, boltedor riveted to their respective margins, and the parts strengthened by tie-rods or bolts W". The drum is provided with blowoff pipes Y, extending from both directions toward the center, as shown in Fig. 2, and perforated to permit the passage of the mud or impurities. They are provided withvalves Y. The drum has man'holes provided with heads Z, as usual. The receiver has handholes provided with heads S, through which a hose may be inserted to wash off the tubes.

W e claim as our invention-- 1. In a feed-water heater,the combination of the horizontal receiver, steam-chamber at each end of the receiver, longitudinal steam-tubes connecting the chambers, supply and exhaust steam pipes communicating with the chambers, water pipes communicating with the chambers, water-pipes connected to the receiver, mud-drum located at the bottom of the receiver, and blow-off pipes extending into the drum, substantially as set forth.

2. The combination, with a horizontal receiver, of a mud-drum located beneath it and parallel therewith, the top of said drum being cut away and the bottom of said receiver correspondingly cut away for forming direct communication between them, substantially as set forth.

3. The combination, with a' horizontal receiver, of a mud-drum located beneath it and parallel therewith, the said drum having its I top part cut away throughout its length and the said receiver its bottom part correspondingly cut away and the angle-irons and rivets for uniting the receiver and drum, substantially as set forth.

4.. In a feed-water heater, the combination of the horizontal receiver, steam-chamber at each end of the receiver, longitudinal steamtubes connecting the chambers, supply and exhaust steam pipes communicating with the chambers, water-pipes connected to the receiver, mud-drum located at the bottom of the receiver, and perforated bloW-ofi pipes extending into the drum, substantially as set forth.

5. In a feed-water heater, the combination of the horizontal receiver, steam-chamber at each end of the receiver, longitudinal steamtubes connecting the chambers, supply and exhaust steam pipes communicating with the chambers, water-pipes communicating with the receiver, mud drum located at the bottom of the receiver, and angle-plates connecting the drum to the receiver, substantially as set forth.

6. In a feed-water heater, the combination of the horizontal receiver, steam-chamber at each end of the receiver, longitudinal steamtubes connecting the chambers, supply and exhaust pipes communicating with thesteamchambers, water -pipes communicating with the receiver, mud-drum located at the bottom of the receiver, angle-plates connecting the drum to the receiver, and the stay-bolts passing through the upper part of the drum connecting the angle-plates, substantially as shown and described.

7. In a feed-water heater, the combination of a horizontal receiver, a mud-drum located beneath it and parallel therewith, and having direct communication therewith throughout its length, as described, and a blow-off pipe 0
